Hot melt adhesive tapes for filling seams between adjacent
dry-wall construction boards and for other purposes

ABSTRACT

A SEAM SEALING TAPE TO FILL VOIDS BETWEEN ABUTTING, SECTIONS OR CRACKS IN WALL BOARD OR SIMILAR MATERIALS IN A WALL OR CEILING CONSTRUCTION, INCLUDING A PAPER OF OTHER SUPPORTING TAPE COATED ON ONE SURFACE WITH A HOT MELT ADHESIVE WHICH IS A SOLID AT ROOM TEMPERATURE BUT SUSCEPTIBLE OF MELTING AND PLASTIC FLOW BY THE APPLICATION OF HEAT TO THE UNCOATED SURFACE OF THE TAPE. THE ADHESIVE IS DISPOSED ON THE SUPPORTING TAPE IN OME OF TWO FORMS, THAT IS, EITHER AS A CONTINUOUS LAYER OR COATING OR IN THE FORM OF CONTINUOUS BEADS DISPOSED IN PARALLEL RELATION ONE TO ANOTHER ALONG THE LENGTH OF THE TAPE. IN EITHER FORM THE ADHESIVE IS DEPOSED ON THE TAPE IN SUCH MANNER AS TO PROVIDE A MAXIMUM AMOUNT OF ADHESIVE ALONG THE CENTER LINE OF THE TAPE SO THAT, WHEN THE TAPE IS LAID OVER A VOID WITH THE ADHESIVE SIDE DOWN AND HEAT SUPPLIED AS WITH A HOT IRON, THE VOID CAN BE RAPIDLY FILLED AND COVERED ON A SINGLE OPERATION. THE RESULTING SEALED SEAM REQUIRES NO DRYING STEP AND CAN BE COMPLETELY OBSCURED BY PAINTING OR BY THE APPLICATION OF SPACKLING COMPOUNDS IMMEDIATELY AFTER THE SEALING OPERATION.

Box 511, Kingsport, Tenn. 37601 Filed Nov. 16, 1970, Ser. No. 89,676 Int. Cl. B32b 1/04, 29/06, 31 /20 US. Cl. 161-418 2 Sheets Drawing. 14 Pages Specification A seam sealing tape to fill voids between abutting sections or cracks in wall board or similar materials in a wall or ceiling construction, including a paper or other supporting tape coated on one surface with a hot melt adhesive which is a solid at room temperature but susceptible of melting and plastic flow by the application of heat to the uncoated surface of the tape. The adhesive is disposed on the supporting tape in one of two forms, that is, either as a continuous layer or coating or in the form of continuous beads disposed in parallel relation one to another along the length of the tape. In either form the adhesive is disposed on the tape in such manner as to provide a maximum amount of adhesive along the center line of the tape so that, when the tape is laid over a void with the adhesive side down and heat applied as with a hot iron, the void can be rapidly filled and covered in a single operation. The resulting sealed seam requires no drying step and can be completely obscured by painting or by the application of spackling compounds immediately after the sealing operation.
